Method Summary

static String	getEmbeddedString(String str, int afterDelims, char delim) Method for parsing substring embedded by constant delimeters.
static int	getEmbeddedStringAsInteger(String str, int afterDelims, char delim) Get the int value of the substring contained between the afterDelims delimiter occurence and the next one
static String	getEmbeddedStringWithoutDots(String str, int afterDelims, char delim) Method for parsing substring embedded by constant delimeters Because getEmbeddedString() support "." for image button, this method do the the same, but ignore dots.
static Vector	splitString(String str, String delimeter) Get a Vector object containing all the tokens related to the input string, splitted using the input delimiter.

Method Detail

getEmbeddedString

public static String getEmbeddedString(String str,
                                       int afterDelims,
                                       char delim)

Method for parsing substring embedded by constant delimeters.
consider the following string s: ac_update_3_12

  getEmbeddedString(s, 0, '_') ==> "ac"
  getEmbeddedString(s, 1, '_') ==> "update"
  getEmbeddedString(s, 2, '_') ==> "3"
  getEmbeddedString(s, 3, '_') ==> "12"
  getEmbeddedString(s, 3, '_') ==> will throw a Runtime Exception
 

Parameters:

str - the string to parse

afterDelims - the delimiter occurence where to start to parse

delim - the delimiter string

Returns:

the substring contained between the afterDelims delimiter occurence and the next one

getEmbeddedStringAsInteger

public static int getEmbeddedStringAsInteger(String str,
                                             int afterDelims,
                                             char delim)

Get the int value of the substring contained between the afterDelims delimiter occurence and the next one

Parameters:

str - the string to parse

afterDelims - the delimiter occurence where to start to parse

delim - the delimiter string

Returns:

the int value of the substring contained between the afterDelims delimiter occurence and the next one

getEmbeddedStringWithoutDots

public static String getEmbeddedStringWithoutDots(String str,
                                                  int afterDelims,
                                                  char delim)

Method for parsing substring embedded by constant delimeters
Because getEmbeddedString() support "." for image button, this method do the the same, but ignore dots. It's a patch and must be revised in the next cleanup... #checkme
consider the following string s: English-001:param1, param2

  getEmbeddedString(s, 0, '_') ==> ""
  getEmbeddedString(s, 1, '_') ==> ""
  getEmbeddedString(s, 2, '_') ==> ""
  getEmbeddedString(s, 3, '_') ==> ""
  getEmbeddedString(s, 3, '_') ==> will throw a Runtime Exception
 

Parameters:

str - the string to parse

afterDelims - the delimiter occurence where to start to parse

delim - the delimiter string

Returns:

the substring contained between the afterDelims delimiter occurence and the next one

splitString

public static Vector splitString(String str,
                                 String delimeter)

Get a Vector object containing all the tokens related to the input string, splitted using the input delimiter.

Parameters:

str - the string to split

delimeter - the delimiter string

Returns:

a Vector object containing all the tokens related to the input string
